## Connection (mcpServers)

```json
{
  "mcpServers": {
    "sic-codes": {
      "type": "http",
      "url": "https://siccodes.co.uk/api/mcp"
    }
  }
}
```


## Trust

- hygiene: 100
- liveness: 0
- freshness: 65
- provenance: 80
- drivers: +repository +namespace-matches-repo -unreachable(13 failures) ~updated-164d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality –/100 (not scored)

Not scored: fewer than three checks apply, usually because no remote answered a credential-free probe or the server is a local package.

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: n/a (weight 30)

- n/a `tools.descriptions`, `tools.description_length`, `tools.schemas`, `tools.annotations`, `tools.directory_hints`, `tools.token_cost`, `tools.api_dump`: tool list unknown (behind auth, not probed, or empty)

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool list unknown

### dependencies: 67 (weight 15)

- pass `deps.known_vulns`: no known advisory in 98 resolved packages
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 1 known advisory (GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.31.0 or later
- pass `deps.resolvable`: sic-codes-mcp@1.0.0 resolved: 98 packages

- tools: unknown
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.jackmmaher/sic-codes.svg)](https://protogrid.dev/servers/io.github.jackmmaher/sic-codes)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
